What reading level is Hygiene book?
To quickly assess the difficulty of the text, read a short excerpt:
The wetted perimeter is that part of the circum- ference of the pipe which is in contact with the fluid. The hydraulic mean depth in circular pipes, running full or half full, is one-fourth of the diameter.
The area of an egg-shaped sewer can be calculated by squaring the radius of the larger circle and multiplying by 262 THE ULTIMATE DISPOSAL OF REFUSE AND EXCRETA.
4'6 ; the discharge in cubic feet per second for egg-shaped sewers flowing two-thirds full can be calculated from the formula Q = ...zSsjd^ji where d is the diameter of the larger circle, / is the fall, and / is the length. The velocity of flow in feet per second through an egg-shaped sewer can be expressed as being 128 X 10 VH 7 X VF, where H is the hydraulic mean depth, F is the fall, and 128 is a constant derived from the ratio of the coefficients for acceleration from gravity and for roughness of surfaces.

Sewer Air. — In well-constructed sewers, where there is no deposit and the sewage is allowed to flow away without any obstacle to the outlets, the air is much better than might be expected.
